Abstract

The effect of B additions on the structure and mechanical and tribological properties of Cu coatings produced by magnetron sputtering from mosaic targets has been investigated. It has been shown that the introduction of B results in structure refinement of the coatings. The hardness, elasticity modulus, elastic recovery, and plasticity index of Cu-B coatings have been determined. It has been established that the introduction of 7-15 at % of boron favors a decrease in the coefficient of friction and reduced wear. It has been shown that high tribological characteristics of coatings in the Cu-B system are connected with the formation of solid H₃BO₃ lubrication on the coating surface.
